Use of amphibians to define riparian zones of headwater streams
Bibliographic record
Abstract
Riparian areas are known for their high species richness and their influence on ecological processes. However, riparian zones are difficult to define because of their ambiguous borders. Defining riparian zones by examining habitat use of species that require both terrestrial and aquatic environments is one method that has not been thoroughly examined. We sampled amphibians in Maine, USA, with pitfall traps located at five distances (1, 8, 18, 28, and 33 m) from 15 headwater streams. We captured 1897 amphibians of 10 species over 73 536 trap-nights. We used a repeated-measures analysis of variance to determine if species' capture rates varied among pitfall-trap locations. The highest numbers of three species, spring salamander (Gyrinophilus porphyriticus), two-lined salamander (Eurycea bislineata), and dusky salamander (Desmognathus fuscus), were captured in trap locations closest to the streams. Total species richness and average species richness were highest in the trap location located closest to the stream. We conclude that the riparian zone along headwater streams, as defined by amphibian species richness and abundance, is relatively narrow (79 m).

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
